I don't know much about Bytejail or their offering; but I'd say one major, non-technical difference is that Bytejail is a German company with servers located entirely outside of the US. In theory, this makes search-and-seizure of customer data subject to German statutes, which are currently much stronger than US law in terms of privacy. Take a look at SpiderOak's privacy policy, under the "Disclosure" section (https://spideroak.com/policy/privacy-policy https://spideroak.com/policy/privacy-policy): >SpiderOak's policy is to notify a user of a request for their personal data stored on our servers prior to disclosure unless prohibited from doing so by statute or court order [e.g. U.S.C. § 2705(b)]. That would be NSLs.
